Relaxor ferroelectrics, which are often lead-based. These materials have mechanical and electrical properties that are useful in applications such as sonar and ultrasound. The more scientists understand about the internal structure of relaxor ferroelectrics, the better materials we can develop for these and other applications.
Scientists at the Mainz University Medical Center and the Max Planck Institute for Polymer Research (MPI-P) have developed a new method to enable miniature drug-filled nanocarriers to dock on to immune cells, which in turn attack tumors.
gold nanoparticles, coated with a semiconductor, can produce hydrogen from water over four times more efficiently than other methods – opening the door to improved storage of solar energy and other advances that could boost renewable energy use and combat climate change, according to Rutgers University–New Brunswick researchers.
The research involved kinesin proteins: tiny, protein-based motors that interact with microtubules inside cells. The motors convert chemical energy into mechanical energy to generate the directional movements and forces necessary to sustain life. Microtubules are microscopic tubular structures that have two distinct ends: a fast-growing plus end and a slow-growing minus ends. Microtubules help make up a cell’s skeleton.
X-Ray Experiment – Over the last decade, scientists have used supercomputers and advanced simulation software to predict hundreds of new materials with exciting properties for next-generation energy technologies. Now they need to figure out how to make them. To predict the best recipe for making a material, they first need a better understanding of how it forms, including all the intermediate phases it goes through along the way – some of which may be useful in their own right.
In the maze of our brains, there are various pathways by which neural signals travel. These pathways can go awry in patients with neurological and psychiatric diseases and disorders, including epilepsy, Parkinson’s, and obsessive-compulsive disorder. Researchers have developed new therapeutic strategies to more precisely target neural pathways involved in these conditions, but they often require surgery.
Scientists from The University of Texas at Austin took an important step toward safer gene editing cures for life-threatening disorders, from cancer to HIV to Huntington’s disease, by developing a technique that can spot editing mistakes a popular tool known as CRISPR makes to an individual’s genome. The research appears today in the journal Cell.
Scientists discovered the phenomenon 30 years ago, but the mechanism for superconductivity remains an enigma because the majority of materials are too complex to understand QPT physics in details. A good strategy would be first to look at less complicated model systems.
Quantum computers will need analogous hardware to manipulate quantum information. But the design constraints for this new technology are stringent, and today’s most advanced processors can’t be repurposed as quantum devices. That’s because quantum information carriers, dubbed qubits, have to follow different rules laid out by quantum physics.
Researchers at Caltech have developed an artificial neural network made out of DNA that can solve a classic machine learning problem: correctly identifying handwritten numbers. The work is a significant step in demonstrating the capacity to program artificial intelligence into synthetic biomolecular circuits.
Nanoscale Kirigami has taken off as a field of research in the last few years; the approach is based on the ancient arts of origami (making 3-D shapes by folding paper) and kirigami (which allows cutting as well as folding) but applied to flat materials at the nanoscale, measured in billionths of a meter.
